I have CPU left led light error (A parity alarm occurred in a RAM on the main CPU PC board). Axis board light up all three red leds or two rightones.
The problem came when the machine was unused for 3 months and robot batteries were empty. MAIN/AXIS module battery was 3,0 V
Fault comes when I coldstart and go ie. file menu, alarm menu .... almost everywhere
BMON and EMON works. I have not done yet TEST CMOS or TEST MEM because they will destroy the contents of CMOS RAM. I know there are good files in CMOSRAM, but I have not figured out how to get them out.
I can only get one file out SYSVARS.SV (39kt) with controlled start/bmon/FCTN button/save. SYSVARS.SV file comes out then red ligh at CPU board and system freezes. SYSVARS.SV seems to be OK (kconvars.exe check)
1. Is it possible to get R-J to work without costly Fanuc contact if I change CMOS daughterboards and load SYSVARS.SV ?
2. Is it possible to make SYSMACRO.SV, SYSMAST.SV, SYSSERVO.SV later ? (a lot of work i think :D)
(When I bought this robot I did not get any files. There was no possibility save files at the beginning, but now I have PC, RS232C cable and Kfloppy.
I do not need user software back. The only purpose is to get the robot to move. )
